Win10 system Chkdsk disk repair tool command Daquan

Chkdsk is a disk repair tool that comes with the Microsoft operating system. When necessary, Chkdsk can detect and repair Windows disks. In the past operating systems, there were not many Chkdsk commands, but in the Win10 system, multiple Chkdsk commands were added. The Chkdsk command can be used to maintain the hard disk. Even if the hard disk fails, Chkdsk will repair the hard disk. .

Microsoft continues to improve NTFS health mode and file system corruption repair methods to minimize the running time of Chkdsk, which is an advantage that Win7 and previous systems do not have. If you want to run this tool manually, you need to run the command prompt as an administrator. The command format is as follows:

Note that the above parameters can be connected multiple times, and there must be spaces between different parameters; you can also directly Run the command in the path with the following format:

chkdsk /parameter:

Specifically, add the following parameters:

/scan - Run an online scan on the specified partition .

/spotfix - Runs a live fix on the specified volume.

/forceofflinefix - Bypass all online fixes; all issues must be added to the offline repair queue (eg Chkdsk /spotfix) and need to be used with “/scan”.

/perf - Use more system resources to complete the scan as quickly as possible, which may reduce the efficiency of other tasks running on the current system.

/sdcleanup - Collect and clean up unwanted security descriptor data and use it with “/f”.

/offlinescanandfix - Runs an offline scan on the specified volume and fixes the error if a problem is found.

In Windows 10, Chkdsk has added command parameters for FAT/FAT32 and exFAT partition formats, as follows:

/freeorphanedchains - Free any isolated cluster chains instead of restoring them Content.

/markclean - If no problems are found, the volume will be marked normally, even if “/f” is not set.

In addition: some of the "historious" parameters need to be understood, such as the above mentioned parameter description "/f", etc., the specific content is as follows:

/f - Fix errors on the disk. It should be noted that this parameter must be locked to the disk, otherwise the tool will display a message asking if you want to check the drive the next time you restart your computer.

/v - Displays the name of each file in all directories when checking the disk.

/r - Find bad sectors and recover readable information. You must also lock the disk.

/x - Use only on NTFS. If necessary, first force the volume to be unmounted, all open handles for that drive are invalid, and /x also includes the /f function.

/i - Use only on NTFS. Perform a lesser check on the index entries, reducing the amount of time spent running chkdsk.

/c - Use only on NTFS. Skip cycle checking in the folder structure to reduce the amount of time it takes to run chkdsk.

/l[:file size] - used only on NTFS. Change the size of the log file to the size entered by the user. If you omit this parameter, /l displays the size of the current log file.

/? - Display help at the command prompt.

It should be noted that the Chkdsk command can only find logical errors in the file system, but not physical disk errors. To find physical disk errors (such as bad sectors), you need to run ScanDisk.

语:

The above are all the commands for the Chkdsk disk repair tool in the Win10 system. If you are often engaged in contact installation, replacement of hard drives and other professional work, this type of command is for you. Need to know.
